ios10，Swift 3和Firebase推送通知（FCM）

Question

我很努力地顯示我從FCM通知控制檯發送給我的設備的推送通知。我可以看到設備正在接收的通知，因爲我可以看到我發送「test8」

Connected to FCM. 
%@ [AnyHashable("notification"): { 
    body = test8; 
    e = 1; 
}, 

消息但是，如果我的應用是在我沒有得到通知顯示在前臺或後臺沒關係。

我在info.plist中添加了「所需的背景模式 - 應用程序下載內容以響應推送通知」。我的證書是正確的，我沒有問題生成一個令牌。我的應用程序正在接收通知，但沒有顯示它們。

我一直在嘗試自己研究和解決這個問題，但我有問題。任何幫助或建議將不勝感激。

裏面方法didRegisterForRemoteNotificationsWithDeviceToken，添加以下代碼：

func application(application: UIApplication, didRegisterForRemoteNotificationsWithDeviceToken deviceToken: NSData) { 
    let tokenChars = UnsafePointer<CChar>(deviceToken.bytes) 
    var tokenString = "" 

    for i in 0..<deviceToken.length { 
     tokenString += String(format: "%02.2hhx", arguments: [tokenChars[i]]) 
    } 

    FIRInstanceID.instanceID().setAPNSToken(deviceToken, type: FIRInstanceIDAPNSTokenType.Unknown) 

    print("tokenString: \(tokenString)") 
} 

而且不要忘記啓用推送通知內能力。

你需要移動

application.registerForRemoteNotifications() 

它不應該是別人的內部。

// [START register_for_notifications] 
    if #available(iOS 10.0, *) { 
     let authOptions : UNAuthorizationOptions = [.Alert, .Badge, .Sound] 
     UNUserNotificationCenter.currentNotificationCenter().requestAuthorizationWithOptions(
      authOptions, 
      completionHandler: {_,_ in }) 

     // For iOS 10 display notification (sent via APNS) 
     UNUserNotificationCenter.currentNotificationCenter().delegate = self 
     // For iOS 10 data message (sent via FCM) 
     FIRMessaging.messaging().remoteMessageDelegate = self 

    } else { 
     let settings: UIUserNotificationSettings = 
      UIUserNotificationSettings(forTypes: [.Alert, .Badge, .Sound], categories: nil) 
     application.registerUserNotificationSettings(settings)    
    } 

application.registerForRemoteNotifications()

對我來說是缺少entitlements文件，所以在項目的Capabilities，你必須點擊修復問題。 Xcode會爲你設置文件。
